Doing an extra PER/LHR trip per roster without night credits and getting zero overtime for doing a 19 hour plus duty is a massive sacrifice without getting anything major for the trade off
The trade off is a future flying for Qantas.
As stated above, comparing A330 and B767 hourly rates against the 787 is not a valid comparison. These aircraft are not capable of flying the same sectors. A more valid commment is that if you insisted on maintaining the same pay rate as 767 or A330 and applying the same overtime and night credits the aircraft would not be flown by mainline pilots under the long haul EBA.
